Venus638FLPx is a high performance, low cost, single
chip GPS receiver targeting mobile consumer and cellular
handset applications. It offers very low power
consumption, high sensitivity, and best in class signal
acquisition and time-to-first-fix performance.<p>
Venus638FLPx contains all the necessary components of
a complete GPS receiver, includes 1.2dB cascaded
system NF RF front-end, GPS baseband signal processor,
0.5ppm TCXO, 32.768kHz RTC crystal, RTC LDO
regulator, and passive components. It requires very low
external component count and takes up only 100mm2
PCB footprint.<p>
Dedicated massive-correlator signal parameter search
engine within the baseband enables rapid search of all the
available satellites and acquisition of very weak signal. An
advanced track engine allows weak signal tracking and
positioning in harsh environments such as urban canyons
and under deep foliage. The self-contained architecture keeps GPS processing off
the host and allows integration into applications with very
little resource.<p>
